Vulnerability Description
The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity checks."

Xen 安全漏洞
Vulnerability Description
Xen是英国剑桥大学开发的一款开源的虚拟机监视器产品。该产品能够使不同和不兼容的操作系统运行在同一台计算机上，并支持在运行时进行迁移，保证正常运行并且避免宕机。 Xen的PCI后端驱动程序中存在安全漏洞。当程序运行在x86系统上并使用Linux 3.1.x版本至4.3.x版本作为驱动域时，本地攻击者可借助拥有passed-through MSI或MSI-X capable physical PCI设备访问权限和XEN_PCI_OP_enable_msi操作执行权限的系统，利用该漏洞生成连续的WARN消息流
